OUCH. Expensive lesson. Bought in pre-market as it was running up. Yes, I was thrilled that I found a high price stock that was going up fast. Placed my order and my system hiccupped. It filled me at the top of the run instead of at the moment I hit enter. In less than 5 minutes, after restarting the platform, I found the stock had tanked and continued to do so. I realized how huge the loss was and got out, which stopped my trading for the day. VERY expensive lesson to learn about FundTradrr
